Abstract
The invention discloses a method for storing energy by using midnight steam of power plants. The method is as follows: the extra steam of fuel electric plants in midnight is used for driving steamers which directly drive air compressors to run; the air compressors compress and store air in a high-pressure container; and then the high-pressure air is used for driving an electric generator to generate electricity during the day of peak electricity. The method omits the processes of generating electricity and operating electric motors, increases energy transformation efficiency and saves equipment investments. The invention is used for storing energy, in particular for storing the extra midnight energy of the fuel electric plants.
Description
Technical field
The present invention relates to a kind of method of utilizing the steam accumulation of energy of banking fire power power station, particularly relate to a kind of method of utilizing power plant's steam in late into the night accumulation of energy.
Background technique
Reach at firepower, when nuclear plant's power supply in the late into the night is more than needed in wind-force, wave, tidal power generation, energy need be stored, utilizing pressurized air to carry out accumulation of energy is a kind of method commonly used.Patent Office of the People's Republic of China is in the invention of application number 200410022747.3 denominations of invention " utilizing the Caes plant of abandoned mine " of 2005.12.14 bulletin, a kind of method of utilizing the pressurized air storing energy is disclosed, though this method has also reached the purpose of storing energy, but this method is to utilize electricity to drive generator for electricity generation earlier, utilize electric energy to drive the motor rotation again, motor drives air compressor pressurized air, complex process again, investment is big, and energy consumption is big.Increasing along with to energy requirement presses for the high method of utilizing steam more than needed in power plant's late into the night of a kind of energy conversion efficiency.
Summary of the invention
The objective of the invention is to solve the shortcoming that exists in the existing Caes technology, a kind of method of utilizing power plant's steam in late into the night accumulation of energy is provided, utilize method provided by the present invention to carry out accumulation of energy, the little investment instant effect, energy consumption is little.
For this reason, the invention provides a kind of method of utilizing power plant's steam in late into the night accumulation of energy, comprise power plant's steam in the late into the night, air compressor, described method is that the steam more than needed in thermal power plant when utilizing the late into the night promotes steamer, steamer directly drives the air compressor running, air compressor is stored in the high-pressure bottle after with air compression, when peak times of power consumption on daytime again with the generating of high-pressure air pushing generator.And present method is to utilize the generating of steam pushing generator earlier, drive motor then, motor drives air compressor again and carries out air compression, adopts this method to save generating and two processes of motor operation, has improved energy conversion efficiency and has saved equipment investment.
Utilize in the method for power plant's steam in late into the night accumulation of energy at another kind provided by the invention, the rotating shaft of described steamer is the rotating shaft of air compressor.With the rotating shaft of steamer and the rotating shaft of air compressor is that an axle can reduce the mechanical transmission link altogether, has reduced transmission link and has just improved energy conversion efficiency.
The method of utilizing power plant's steam in late into the night accumulation of energy provided by the invention is compared with existing method and is had the following advantages:
1. energy conversion rate height: method provided by the present invention has reduced generating and two links of motor operation, has improved the conversion efficiency of energy;
2. minimizing equipment investment:, can reduce equipment investment owing to reduced generating and two links of motor operation.
Below by accompanying drawing, embodiments of the invention are described, can be expressly understood more that the present invention conceives really.
Description of drawings
Accompanying drawing is a kind of schematic representation that utilizes the method for power plant's steam in late into the night accumulation of energy provided by the invention.
Embodiment
With reference to accompanying drawing, wherein described a kind of schematic representation that utilizes the method for power plant's steam in late into the night accumulation of energy provided by the invention: in the time of at dead of night when the generated energy in thermal power plant is more than needed, the steam in thermal power plant is transported to promotion steamer 2 rotations in the steamer 2 from boiler 1, steamer 2 drives air compressor 3 rotations by mechanical transmission, and air compressor 3 is stored being sent to after the air compression in the air compression tank 4.When daytime during peak of power consumption, the high-pressure air that is stored in air compression tank 4 is discharged the pushing generator generating, thereby reach the purpose that makes full use of the energy.
Above described embodiment be that the present invention will be described, be not that the present invention is limited.Design that the present invention is claimed and scope all are documented in claims of the present invention.
Claims (2)
1. method of utilizing power plant's steam in late into the night accumulation of energy, it is characterized in that: described method is that the steam more than needed in thermal power plant when utilizing the late into the night promotes steamer, steamer drives the air compressor running, air compressor is stored in the high-pressure bottle after with air compression, when peak times of power consumption on daytime again with the generating of high-pressure air pushing generator.
2. the method for utilizing power plant's steam in late into the night accumulation of energy according to claim 1 is characterized in that: the rotating shaft of described steamer is the rotating shaft of air compressor.
